Awesome Lego

If you want to remove pencil marks from paper, you need a good eraser. While good old elbow grease usually does the trick, there are motorized erasers too. LEGO builder Dr. Engine thought it would be fun to build a few overengineered Technic machines to see which would do the best job at erasing graphite from paper. Which design is your favorite?

What’s better than a LEGO tank? A LEGO tank that can drive into the water, of course. Brick & Gear shows off the latest version of his Behemoth, a remote-controlled Technic vehicle powered by four motors – two for the tracks and two for water propulsion. After some bathtub testing, he drove it into a lake to see what it could do.

This jumbo-sized Mario Kart LEGO model has a whopping 1972 pieces, and comes together to build a 12.5″ long version of Mario behind the wheel of his standard racing Kart. Mario has a poseable head and arms, and his kart sits on an angled stand to give it a sense of movement. Pre-orders start shipping 5.15.2025.

A standard LEGO minifig stands roughly 1.6″ (4 cm) tall. Maker of many crazy things, The Q, shows us how he used a 3D printer to produce the parts needed to make a giant minifig bigger than he is. Before making the XXL model, he printed small, medium, large, and XL figs. We can only imagine how much time and filament it took to make the biggest one.

This awesome LEGO version of Tyrannosaurus Rex measures over 41″ long and 12″ tall. The 3145-piece model is wonderfully detailed from its teeth to its tail and includes two minifigs and a display plaque detailing the most feared dinosaur of the late Cretaceous period. Drops 3.15.2025, with an early release on 3.12 for LEGO Insiders.

LEGO fans know that there are certain building techniques that are considered “legal” and “illegal.” Half As Interesting explains how LEGO designers create new sets, starting with building prototypes with off-the-shelf parts. As they build, there are certain rules they abide to ensure models stay sturdy and stable, and the bricks won’t deform.

This custom build from Brick Machines combines two of our favorite pastimes – LEGO and candy. Built primarily from LEGO Technic and Mindstorms parts, the tabletop factory includes a mechanical candy hopper, an optical color sorter, a conveyor belt, color-matched lights, and an elevator to keep the sweet treats flowing in an endless loop.

A coil gun is a weapon that uses electromagnets to accelerate a metal projectile through its barrel. It’s possible to build your own, but the high-voltage electricity involved can be dangerous. Using the utmost caution, Jamie’s Brick Jams built a slightly less deadly coil gun using Technic parts, a bunch of 9-volt batteries, and some 100-volt capacitors.

Brick Machines is back with another awesome LEGO Technic and Mindstorms creation. He shows how he built a fully functional LEGO laptop with a working keyboard and a mouse that uses a magnetic X/Y track and a hall-effect sensor to detect its position and button clicks. Both the keyboard and mouse pad have programmable RGB backlighting.

The Battle of Geonosis is one of the most pivotal moments in The Clone Wars. This incredible LEGO build pays tribute to the setting of this epic confrontation. Solid Brix Studios shared this time-lapse video of his 250,000+ piece diorama during its 2-year build. The 15-foot-long model is packed with details, and the textures of the landscape are incredible.

The kinds of vehicles you can make with LEGO parts are amazing. This tank design from Brick Technology is one of the most impressive LEGO vehicles we’ve seen. It has a 3-speed manual transmission and tracks with a self-adjusting suspension. On top, it packs a motorized turret with a rapid-fire brick launcher. The whole shebang is driven with a PS4 controller.

LEGO has revealed a number of additions to its Formula 1 race car collection. Among the new models are large Technic versions of the Ferrari SF-24 and Oracle Red Bull Racing RB20, as well as small Speed Champions cars from Mercedes-AMG, McLaren, Williams, BWT Alpine, and more. There’s also an F1 transporter truck with RB20 and AMR24 race cars.

Andrew from Hypno Motion makes some of the best stop-motion LEGO animations we’ve seen. His specialty? Cooking up delectable dishes from the iconic plastic bricks. Working with lots of small parts, his animation style is smooth as silk. We could watch his LEGO coffee video all day. His behind-the-scenes videos are worth a watch too.

Some factories have fancy conveyor systems that can move items in different directions. We’ve also been wowed by Disney’s Holotile floor. Banana Gear Studios’ LEGO treadmill takes inspiration from the Holotile, but uses discs that tilt at different angles items instead of rotating them. The mini treadmill can only move tiny objects, but it could be expanded.

Greg Saniatan aka slopsmcgee created this wonderful stop-motion animation that makes it look like he’s making a LEGO flower pot out of clay on a potter’s wheel. He made the clip to help promote the LEGO Botanical Collection, including the vibrant Chrysanthemum set shown in his video. Greg previously “painted” The Great Wave off Kanagawa.

A word that’s the same forward as backward is called a palindrome. If the word spells a different word backward, it’s colloquially known as an emordnilap. To demonstrate this wordplay, Michael from Vsauce built a LEGO Technic machine that can reverse words with a simple motion. The device transposes each letter and flips it so it stays right-side-up.
